The implementation of the invention

Next will be described embodiments of the invention or elements of the invention, which is illustrated in the attached drawings. In General, throughout the drawings the same or similar reference positions are used to refer to the same or similar items.

Fig.1, 2, 3 and 5 are shown to illustrate the various directions such as a direction 184 forward direction 186 ago, direction 180 to the left (Fig.2 and 5) and the direction 182 to the right (Fig.2 and 5). It is clear that the directions don't necessarily show on the "front part", "rear", "left" or "right side" of the machine or instrument, and show the relative positions of the components or elements that will be described below.

Fig.1 shows a coupling device 10, intended for connection of the primary driving element 114 with the working tool 190. The connecting device 10 may include a first connection Assembly 110 containing the first and second supporting means 144A, a and rotary wedging means 300, while each of these funds is made with the possibility of connection with the second connecting node 112. The second connection Assembly 112 may include first and second means 146a, 150A in the form of notches and the third supporting means 152a, each of these funds is made with the possibility of connection with the first connection node 110.

One of the connecting nodes 110 can be attached to the primary drive element 114, for example, so that the primary drive element 114 may apply a pulling force to the working tool 190 via the connecting device 10. As shown in Fig.1, the primary drive element 114 may, for example, be an operating handle 114 digger, ditcher, forklift or similar device. Connection Assembly 110, shown in Fig.1 may be coupled with an operating handle 114 in the front section 185 of the connecting node 110 via the first swivel 168. For example, the first rod 198 may be coupled to the connecting node 110, and the operating handle 114 through a pair of front holes 202 (perednik� holes 202A left side and front openings 202b right side), which are made in the connection Assembly 110, and holes in the working of the handle 114, and the specified connection is intended for retention of the handle 114 in operable coupling with a connecting node 110.

Connection Assembly 110 may be coupled to linkage 176 at the rear of 187 connecting node 110 using a second swivel 172. For example, the second terminal 200 may be inserted into a pair of rear holes 204 (rear hole a left side and the rear opening 204b right side), which are made in the connection Assembly 110, and the holes in the lever mechanism 176, and the specified connection is designed to hold the lever mechanism 176 in operable coupling with a connecting node 110. A lever mechanism 172 can be attached to the operating handle 114 and may be additionally attached to the hydraulic cylinder for the purpose of additional managed operating force to the working tool 190 via the connecting device 10.

First bearing means 144 (144A, 144b) may be positioned on the connection Assembly 110 in a relatively front portion 185 of the connecting node 110. For example, in one embodiment, the front rod 194 may be connected, for example, by means of a welded joint with the front part 185 of the connecting node 110, so that the left part 14a of the rod and the right side 144b of the rod can form the first front left support element 144A and the second right front support element 144b, respectively.

Second supporting means 148 (a, 148b) can be placed at the connection Assembly 110 in a relatively rear portion 187 of the connecting node 110 at a distance D1 (Fig.3) from the first reference means 144A, 144b. For example, in one embodiment, the rear rods a, 148b is made with the possibility of connection, for example by means of a welded joint, and the rear end 187 of the connecting node 110, so that the rear left rod a and rear right rod 148b may form a first left rear support element a and second right rear support element 148b, respectively.

Another connection Assembly 112 may be attached to a running tool 190, for example, by means of a welded joint 208 (Fig.1).

First means 146 (146a, 146b) in the form of recesses may be positioned in the second connecting node 112 in a relatively front portion 212 of the connecting node 112. For example, in one embodiment, a pair of front notches 146a, 146b may be formed in the front side 212 of the connecting node 112 to form the first front left recesses 146a and the second right front recesses 146b, respectively. Front left recess 146a and front right recess 146b can be made so that they could be the first front left support element 144A and the second right front support element 144b ώ�tively. In an embodiment of the invention shown in Fig.1, the recesses 146a, 146b are made in the hooks 147a, 147 b that are curved backward.

The second tool 150 (150A, 150b) in the form of notches may be located on the second connecting node 112 in a relatively rear portion 216 of the connecting node 112. For example, in one embodiment, a pair of rear notches 150A, 150b may be formed in the rear portion 216 of the connecting node 112 to form a first left rear recesses 150A and the second rear right recess 150b, respectively. Rear left recess 150A and the right rear recess 150b may be performed so as to position the first rear left pillar a and second right rear support element 148b, respectively.

As shown in Fig.7, in an alternative embodiment, the first supporting means 144A, 144b may be formed of rod 198, which fastens the primary drive element 114 to the first connecting node 110. In such an embodiment, the rod 198 forms part of the connecting node 110 and may be connected to a connecting node 110, for example, using the first and second holes 200A, 200b, made respectively in the front left and front right part of the first connecting node 110. The rod 198 may be attached to the connector�th node 110 and may remain in it, to the ends of the rod 198 extend beyond the left side as 110A and the right side 110b of the first connecting node 110 to form the first front left support member 144 from the first connector 110 and the second front right of the base element 144d of the first connecting node 110, respectively. In this alternative embodiment, the second connection Assembly 112 may also be modified so as to form the first tool with 146, 146d in the form of notches in the hooks 147, 147d, which are curved in the downward direction.

As shown in Fig.1-4, the third bearing means 152 (152a, 152b) can be placed at the connection Assembly 112 in the rear portion 216 of the connecting node 112 at a second distance D2 (Fig.3) that is greater than the first distance D1, from the first abutment means 144A, 144b and means 146a, 146b in the form of notches. In one embodiment, a pair of rear protrusions 152a, 152b may be located, for example by means of a welded joint, on the rear side 216 of the connecting node 112, so that the left rear protrusion 152a and right rear protrusion 152b may form a first left rear support element 152a and second right rear support element 152b, respectively, and they can be designed to interact with the third means in the form of notches comprising a first rear Levu� the recess 154 and the fourth right rear recess 154b, which are located respectively on the left rear and right rear wedging elements 120A, 120B.

As indicated above, wedging the tool 300 may be positioned at the first connecting node 110, for example, at the rear of 187 connecting node 110, and may be intended for coupling with the second coupling node 112.

In one embodiment the wedging tool 300 can include a first rotatable wedging element 120A, conventionally located on the left rear part of the connecting node 110, and a second rotatable wedging element 120B, conventionally located on the right rear part of the connecting node 110.

Rotary wedging elements 120A, 120B may be attached to the first connecting node 110 through the rotary drive mechanism 160, containing the first and second rotatable output shafts 164a, 164b extending outward from the drive mechanism 160 along the axis 140. As shown in Fig.3, the axis 140 may be generally aligned with the Central axis 320 of the support elements 152a, 152b, so that similar supporting elements 152A, 152B, rotary wedging elements are installed at a distance D2 from the first support means 144. Further, the rotary drive mechanism 160 may be located generally on a straight line between the two wedging elements 120A, 120B, e.g.�, generally along the axis 140. Thus, in one embodiment the wedging elements 120A, 120B are positioned at the rear of the second support means a, 148b and arranged to be rotated about the axis 140, located at the rear of the second support means a, 148b.

The rotary drive mechanism 160 may be installed at the first connection Assembly 110, for example, using mounting bolts 304 (Fig.5) passing through the rear plate 324 of the first connecting node 110 and through the seat 328 is attached to the rotary drive mechanism 160. In one embodiment, the rotary drive mechanism 160 may be a hydraulic drive mechanism designed to rotate the rotary output shafts 164a, 164b when the hydraulic pressure from a hydraulic source (not shown).

Each of the rotary wedging elements 120A, 120B may be connected to respective rotary output shaft 164a, 164b, for example via a bolt element 308 is connected through the corresponding hole a, 312b wedging element and the threads located in the threaded hole 314a, 314b of the corresponding output shaft 164a, 164b. Thus, the rotary wedging elements 120A, 120B may choose to rotate with povorotnoye shafts 164a, 164b relative to the first connecting node 110 and relative to the axis 140, for example, when the application of hydraulic force to the hydraulic drive mechanism 160.

As schematically shown by line 326 in Fig.5, in an alternative embodiment, the rotary hydraulic drive mechanism 160 may be replaced by multiple (e.g., two) independent rotary hydraulic drive mechanisms 160A, 160b with independently controlled rotary output shafts 164a, 164b. Thus, the first rotary hydraulic drive mechanism a can be connected to the first wedging element 120A via the first shaft 164a, and the second rotary hydraulic drive mechanism 328b may be connected with the second wedging element 120 through the second shaft 164b regardless of the hydraulic driving mechanism a. In such an embodiment, each of the first and second drive mechanisms a, 328b can be managed independently from each other, for example, via a separate hydraulic lines (not shown) to the independent actuation of the first and second output shafts 164a, 164b and the first and second wedging elements 120A, 120B. Wedging elements 120A, 120 can be managed with the aim of tightening the first and second connection points 110, 112 to each other p�and simultaneous adaptation to the wear of one or more elements of the connecting device 10. Thus, through the use of two separate drive mechanisms a, 328b for the purpose of independent control of the first wedging element 120A and the second wedging element 120B can be achieved more fitting to wear independently for the left side or element of the right side.

As shown in Fig.1-5, each rotatable wedging element 120A, 120B may have a recess 154, 154b, made in an appropriate rotary wedging element 120A, 120B. The notches 154, 154b may be designed for connection with a second connecting node 112 by positioning them in supporting elements 152a, 152b of the third supporting means 152a, 152b of the second connecting node 112, so as to form a third connecting contact area 119 (Fig.3) between the recesses 154, 154b of the first connecting node 110 and support members 152a, 152b of the second connecting node 112.

Each rotary wedging element 120A, 120 may be provided with arcuate wedging surface 122A, 122b, designed, with the gradual rotation of the rotary wedging element 120A, 12B, app for gradually increasing efforts to tighten control means 152a, 152b with the aim of tightening and fastening together of the connecting nodes 110, 112. For example, as shown in Fig.6, when the rotary Zach�anywaysi element 120A is in a first fixed angular position relative to the first connecting node 110, arcuate wedging surface 122A may be located relative to the axis 140 in a generally helically so that the arcuate wedging surface 122A at least partially surrounds the axis 140, are located along the radius of the field R, gradually spaced farther from the axis 140. As shown in Fig.6, the radius R of the arcuate wedging surface 122A can take the first value of R1 is approximately in the position for 12 hours, the radius R may gradually increase along the arcuate wedging surface 122A in the clockwise direction through 90° in the direction of 3 o'clock, and gradually increase along the arcuate wedging surface 122A in the clockwise direction over the next 90° in the direction of 6 hours.

Wedging elements 120A in Fig.1 and 3 show overall in the "open" positions, ready for the initial connection to the supporting member 152a of the second connecting node 112. However, wedging element 120A shown in Fig.6, depicted V. partially "closed" position in which there is already a connection to the supporting member 152a and rotated in the clockwise direction is slightly smaller than 90°. In one embodiment of the invention in the fully closed position of the wedging element 120A, shown in �IG.6, can be rotated in the clockwise direction by approximately 220° from an initial open position to a fully fixed connection with a support element 152a, so that the tightening torque applied by the arcuate wedging surface 122A may be applied to the supporting element 152a near the position 336, symbolically indicated in Fig.1-6 (for example, the specified position approaches the position for 4 or 5 hours). Thus, arcuate wedging surface 122A wedging element 120A may be formed so that the additional rotation of the wedging element 120A further increases the tightening force acting on the supporting element 152a. Thus, the wedging element 120A may be designed to provide opportunities to further tighten if necessary (with rotation), for example, to adjust for wear of the various connecting elements, such as deterioration of the support element 152, wear wedging means 300, the wear of the rods 148 or 144 or wear grooves 150 or 146.

As shown in Fig.6, in one typical embodiment the arcuate wedging surface 122A, which is in a fixed position, may have a first radius R1, when measured from the axis 140 of rotation, in the first position, to�oroe approaches the position at 12 o'clock, and may have a generally increasing radius R, moving along an arcuate wedging surface 122A in the direction clockwise around the arcuate wedging surface 122A, so that the radius R2 may increase by about 2% when turning on the first 22.5° in the clockwise direction. For example, the radius R1 may be about 29 mm (1.14 inches) and the radius R2 may be about 29.6 mm (1.17 inch). The radius R may similarly be increased (e.g., to increase by a constant percentage) with further movement in the clockwise direction around the arcuate wedging surface 122A. Alternatively, and as shown in Fig.6, the radius R can be increased by increasing the percentage with further movement in the clockwise direction along the arcuate wedging surface 122A, for example so that in the position for 3 hours (offset 90° from the position for 12 hours), the radius R4 will increase by around 4.5% compared to the last of 22.5° from the position for 3 hours - that is, the radius R4 shown in Fig.6 to grow by 4.5% when moving towards the radius R5 shown in Fig.6. In such an embodiment, the radius R of the arcuate wedging surface 122A may further increase, for example, by an amount equal to approximately 6% of the relative�about the last of 22.5° in the direction of 6 hours that is, the radius R7 will increase by 6% when moving towards the radius R8. One effect of this growing degree of increase of the radius R when moving in the clockwise direction around the arcuate wedging surface 122A is that the wedging element 120A tighten around the support element 152a in the direction of clockwise, and further rotation of the wedging element 120A leads to a gradual decrease in the movement with the aim of tightening to the first connecting node 110 in the direction to the second connecting node 112. Moreover, if the hydraulic drive mechanism 160 driving, for example, by a device, controlled by a hydraulic force, with the aim of tightening the connecting nodes relative to each other with wedging means 300 until a specific need tightening efforts, you can achieve improved accuracy to achieve the required tightening efforts.

Industrial applicability

To connect the first connection node 110 with the second connecting node 112 of the first connection Assembly 110 can be attached to the primary drive element 114, for example, by means of hinge joints 168, 172; and the second connection Assembly 112 may be attached to a running tool 190, for example, using Samovodene 208 (Fig.1).

As shown in Fig.1, during the connection of the first connector 110 and the second connector 112, the operator can create the first connecting surface area a, 116b between two nodes 110, 112 by connecting the first support means 144A, 144b of the first connector 110 with the first means 146a, 146b in the form of notches. For example, the operator can create a first mating connection between the first and second connection nodes 110, 112 using the first conditional in the front left support member 144A and the first conditionally front left recesses 146a. For example, the operator can create a second mating connection between the first and second connection nodes 110, 112 using the second conditional in the front right support member 144b and the first conditional right front recesses 146b. It is clear that the first and second mating connections may occasionally be formed essentially simultaneously during the operation of the Assembly.

Next, the operator can rotate the connecting node 110 relative to the first supporting means 144A, 144b in the direction of arrow 332 (Fig.1) up until the second abutment means a, 148b of the first connecting node 110 does not come into contact with the second means 150A, 150b in the form of notches of the second connecting node 112 to create the second connecting contact area 118 (118a, 118b) (Fig.3). For example, the first W�days left pillar I can get in contact with the first rear left recess 150A of the second connecting node 112 to create a third mating connection between the first and second connection nodes 110, 112; and the second rear right support element 148b may come in contact with the second rear right recess 150b of the second connecting node 112 to create a fourth mating connection between the first and second connection nodes 110, 112.

The third connecting contact area 119 (Fig.3) between the first connecting node and its second connecting node can also be created through the third contact means 154, 154b in the form of recesses of the first connector 110 with the third supporting means 152a, 152b of the second connecting node 112.

Further can be powered by a hydraulic rotary drive mechanism 160 for the purpose of (1) rotation of the rotary output shafts 164a, 164b relative to the axis 140 and (2) turning the rotary wedging elements 120A, 120B and arcuate wedging surfaces 122A, 122b relative to the axis 140 to a gradual tightening and fastening together the first and second connection points 110, 112.

As mentioned above, the hydraulic drive mechanism 160 can be controlled or electronic or hydraulic, for example, to tighten the wedging elements 120A, 120B relative to the supporting means 152a, 152b until then, until it is applied a predetermined tightening torque, designed for tightening and fastening together of the connecting nodes 110, 112. Thisway, arcuate wedging surface 122A, 122b can communicate with the target application, while gradually turning wedging elements 120A, 120B relative to the axis 140, gradually increasing efforts to tighten the pole 152a, 152b, thereby the first and second connecting nodes gradually more densely connected to each other.

At least partially due to the relatively spaced (e.g., triangle) the location of the first reference means 144A, 144b, the second calibration means a, 148b and third abutment means 152a, 152b, the delay of the third supporting means (for example, tightening the wedging elements 120A, 120B relative to the third support elements 152a, 152b) can cause simultaneous gradual tightening relative to each other as (1) of the first connector 110 and the second connector 112 to the first connecting contact area 116 and (2) the first connector 110 and the second connector 112 to the second connecting contact area 118. Further, at least partially due to the fact that wedging the tool 300 is located behind the first and second support means 144, 148 and in contact with the second connecting node 112 at a location behind the first and second support means, securing and sethiwan� elements rotatable wedging means 300 and the third supporting means 152 does not require a space between the first and second connection nodes, and specifically between the first and second connecting contact areas 116, 118, so that the first and second connecting nodes 110, 112 (and, thus, the operating handle 114 and a working tool 190) can be located very close to each other.

As is clear from the above description, the arcuate wedging surface 122A, 122b rotary wedging elements 120A, 120B are constructed to cooperate with a second connecting node 112 with a first force when the rotary wedging element is rotated in a first angular position relative to the first connecting node 110, and interact with the second connection with the second node is increased by the tightening torque when the rotary wedging elements 120A, 120B are rotated into a second angular position relative to the first connecting node 110 (e.g., as described above, when the wedging elements 120A, 120B are rotated further about the axis 140 in position full closing).

Even more specifically, in one embodiment of the invention, when the wedging elements 120A, 120B are rotated about the axis 140 from a first open position at approximately 160° or more in the first position tightening, arcuate wedging elements 122A, 122b are pulled relative to each other of the first and second connection nodes by the application of force delaying the third control means 152a, 152b Upon further rotation of the wedging elements, for example for an additional 20° (e.g., 180° from the first open position), second position, tightening, arcuate wedging surface 122A, 122b exert a greater tightening force to the second connecting node 112 via the third bearing means 152, 152b. Similarly, when the arcuate wedging elements to be turned on, for example, for an additional 20° (e.g., at 200° from a first open position), in third position tighten, arcuate wedging surface 122A, 122b exert an even greater tightening force to the second connecting node 112 via the third bearing means 152, 152b. Further, when the arcuate wedging elements rotated even further, for example, for an additional 20° (e.g., at 220° from a first open position), in the fourth position tighten, arcuate wedging surface 122A, 122b exert an even greater tightening force to the second connecting node 112 via the third bearing means 152, 152b.
